Man, I never knew that about the power schemes. Sure enough, what you say is on Intel's site:

This has all been very educational so far. I'll be getting one of those Kill A Watt monitors in the mail tomorrow or Wednesday, so I'll do some testing and see if it's even worth worrying over. It seems that I have to increase my voltage quite a bit to use EIST, which I feel may negate the power savings it would bring. Not to mention the extra cooling needed.
Not if it's properly executed. My rig still require 1.465Vcore to run stable at 3.46GHz,
INDEPENDENT of C1E/EIST. Always stick to default multiplier or you will confuse the speedstep protocol.
So why run C1E and EIST? When your PC isn't running at 100% load, the CPU can throttle back to a lower multiplier and voltage. The result is lower core CPU temperature when the CPU is not under full-load. It is possible to run at a higher Vcore with this strategy because the CPU doesn't have to work at the full-load voltage all the time.
That's the beauty of dynamic overclocking. Higher Vcore on demand. Lower Vcore when idling. Power savings is about 10 watts at the wall.
